While everyone focuses on the FCX10, since January, Yikong sells a new crawler, with a twist ... the first crawler with disk brakes.
Yep, disk brakes on the rear axle ... they call it "Tank Turn", IRL it's called "Cutting Brake".

Sold as RTR ... no manual (you download it with a QR code on the box), no batteries (even for the radio) ... just the truck, some screws, an optional front bumper and the same radio as the FCX10.
SE is entry level with opaque windows, 2-speed gearbox and manual locking-diffs.
Pro is high-end version, with clear windows and interior, 2-speed gearbox, individual locking axles, lighting, more detailled body and "Tank Turn".

Body mimics a G63 with Adventure pack.

Rubber mirrors ... these should last more than one trail.

One screw holding the body shut.

It uses the same electronics as the FCX10, with a different layout on the radio. 2-in-1 ESC with remote light module.

Don't know if FMS plans to but Yikong has a reference for a divorced 11ch receiver ... though not yet available to buy.

Motor is a brushed 550 32T, with a 14T mod0.6 gear. Not Fusion territory but soft enough.

Chassis is of a different breed, all fibered nylon with TVP design ... a bit like a Tamiya on steroïds ... with very little above it. And it's stiff ... as much if not more than my Gen8 and its 1.5mm frame rails.

3-links front, 4-links rear, Panhard bar at both ends ... which makes sense given how the rear as little triangulation.

All aluminum shocks (emulsion) and small portals that will make wheel compatibility easy.

There's also a steering shock as on Absima Sherpa and once Rebel RC Rebelcon, but skinier and stiffer.

Tires are 116mm on 2.2 wheels ... unfortunately glued-on.

Locking mechanism is exposed but being of a sliding style, that shouldn't be an issue. This allows them to offer manual locking diffs on the entry level SE version.

The rear axle is where everything happens ... it has disk brakes !!!
How it works : when switch ch4, the rear diff is unlocked if needed and when you steer, the inside wheel is locked by the rear servo, the other wheel is still free
